Overview
SF6 gas insulated ring main unit(RMU/C-GIS):
Safe ring/plus RMR type SF6 gas insulated ring main unit is integrating with SF6 infill cabinet which gather with LBS, VCB, Fuse, ES, DS,etc.
By the perfect integration of stationary type and flexible expansion, RMR type SF6 gas-insulating compact close metal switchgear(Ring
main unit) with the adoption of the modular design, is suitable for end-user or network node, meanwhile meets the requirement of all kinds of
switching substations cabinet-type transformer substations and cable branch cabinets. It characters on its compact structure, safety and
reliability, longevity and maintenance free.
This product is in conformity with the standards of IEC60420,GB/T11022,GB3804,GB3906.
